.To .all whom, t may concern:

Be it known that I, JAMEs BRANDY, of Lawrence, in the county of Essex, State of Massachusetts, have invented a certain new and useful Improvement in Machines for Making Felt Boots, Shoes, or Stockings, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification ,in whichW Figure 1 is an isometrieal perspective View representing my improved machine in use, or as attached to the card, the ear-d being shown in side elevation; Fig. 2,atop plan view; Fig. 3, a front elevation, Fig. 4, a side elevation; Fig. 5, an isometrical perspective view taken from the side of the machine opposite to that shown in Fig. 4; and Fig. G, a view of the cone or former and its supporting or epe'raiive rolls, a portion of these parts being shown in section.

Likeletters and figures of reference indicate corresponding paris in the different iigures of the drawings.

My invention relates vto that class of felt boot, shoe, or stocking machines in which the cone or former and its supporting or operative rolls are mounted on a carriage or table and moved back and forth horizontally through the are of a circle in front of the card from which the sliver of wool or felting material is received in forniing`the bat; and .it consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a more eifectiye device of this character is produced than ifs new in ordinary use. a lr The nature aud operation nel' thefimprbvement will be readily understood,by` all `conversant with such matters from the following explanation.

In the drawings, A represents ,the card by which the sliver of wool or other fe ting material is produced, and from which the bat is formed; but as this is of the ordinary construction, except as hereinafter set forth, it is not deemed essential to describe the same more fully. Mounted horizontally near one end of the card, in the standards 22, there is ashaft, 20, provided with a pulley, 19, and also at its opposite end with a driving pulley, (not shown,) the driving-pulley being properly connected to the main driving-shaft olr the card. Disposed at the opposite end of the card there is a horizontal shaft, 23, arranged on a plane with the shaft 20, and provided with a pulley, B, and pinion ac, the pulleys 19 and lf3 being connected by the belt 1S. A shaft, U', is tjournaled horizontally in the supports (j, one of these supports being attached to the bed-piece or frame-work ol:` the card A, and the others to the bed-piece 'l5 et' the inachine. A gear, C, is disposed at the outer end of the sha-ft, a pinion, d, at its inner end, and a gear, m, near its inner end, the gear C intermeshing with the pinion .r on the shaft A shaft, H, supported in the standards l, is journaled in parallelism with the shaft G, but on a lower plane, and is provided at its inner end with the gear E and at its outer end with the crank I, the gear E intermeshing with the pinion d on the shaft G. A table. O, has its inner end pivoted at 13 to the bed-piece Y, its outer end being supported on trucks gv, which run on the curved track y, resting on said bed-piece. A head-stock, It, provided with ways is mounted transversely on the outer end of the table O, and arranged to si ide longi tudi nally on 0 form, and are arranged in parallelism on. the

same plane in such amanner that their ends are nearly in contact. rlhey are also larger or of greater diameter at their ends than at their centers, each roll consistingof two conical frustuins of equal dimensions, joined at their apio-es. A shalt, l, is journaled horizontally at the inner end of the table O, heilig supported in the standards n, and provided near its center with the gear D and at one end with the bevel-gear L, the gear D interineshing with the gear m on the shaft G, and both of the latter gears having teeth curved or rounded at their outer ends to permit the table to swing -freely on the pivot 13. A shaft, N, supported in the standards a, is horizontally journaled at right angles to the shaft K on the table .0, and provided at its inner end with the bevelgear M and at its outer end with the bevel- IOO gear i', the gear M intermeshing with the gear l arm 32.

Il on the shaft IC.

Journaled longitudinally and horizontally in the carriage It there is ashaft, Q, provided 5 with the spline 16, gear S, and bevel-gear 27,

the gear S being adapted to slide loiigitudi nally on said shaft, but prevented from turning thereon by the spline, the gear 27 internieshing'with the gear r on the shaft N.

Disposed in the carriage T, and journaled horizontally therein in parallelism with the shaft Q, there is a shaft, 2', provided with the gear 7c, which intermeshes with the sliding` gear S, and also with both of the gears 6 at the center of the .rolls U.

Projecting downwardly from cross-bars 17 on the carriage T there are two arms, l5, one on either side of the gear S, and adapted to slide said gear on the shaft Q as the carriage moves back and forth on the head-stock It, and thereby keep it in engagement with the gear 7o on the shaft e. A pitmanrod, J, is jointed atj to the table O, and at i to the collet 29 on the crank-pin 28 of the crank I, the collet being adapted to turn on the pin, thereby forming a slack joint to prevent the crank from getting caught or stopping on 'either ol' its dead-centers. rlhe rod is also 4 loosely connected to the table at the joint j for the same purpose, and is made adjustable longitudinally by the sleeve e, the body ofthe rod being in two pieces and screwed into the sleeve.

Disposed on the shaftN near theheadstock R there is a fixed cam or eccentric, I, around which passes a strap or annulus, 29, within which the eccentric revolves, said strap being connected to one end of the pitmanrod 3 and the opposite end of said rod jointed to the carriage l at 30. rlhe cone or former NV is so shaped that when laid upon the rolls U its body will be in close contact therewith nearly its entire length, being largest at the center and gradually tapering toward either end, or consisting of two leg-pieces, 4, each provided with afoot-piece, '1), theleg-pieees being united at their tops and the foot-pieces projecting in opposite directions to balance the cone, as best shown in 3 and 6. The cone is also provided at its center with an annular groove, 5, which acts as a guide for the shears in cutting the bat prior to its removal therefrom. A guard, 7, consisting of a thin strip of sheet metal, is placed around each of Vthe rolls U immediately over thel gears (5, to prevent the bat on the cone from being caught in said gears as the rolls revolve,the guard being supported at either end by the carriage'l and bent down at the center between the rolls, so as not to interfere with the action of the cone. (One end ol the guard, broken away to expose the gear 6, is shown in Fig. 5.) A rocker-shaft, lw, is jonrnaled in the standards 26 at either end of the carriage T, said shaft being provided at one end with au arm, h, and counterbalance j, and on the opposite side, near its center, midway between the rolls U with the This fi'm is provided with a coinpressor, b, composed of two cylinders, 11i anid 8l, preferably constructed of sheet metal, an d adapted to revblve independently on the arnl. This compressor should be somewhat longer ihan the floot-piece o, and may consist of one or more cylinders, as desired,although I deen'i two prefc'rable ito a greater number.

Projecting upwardly from either end of, the carriage '.l there is a standard, 33,which rises above the cone NV when said cone is mounted on its rolls U. A bifurcated arm, 8, is jointed to the upper end of each of these standards, and provided with a horizontally-journaled auxiliary compressor,consisting of a short cylinder, 9, made in two sections.

In the use of my improvement the cone or former XV is, placed on the rolls U and power applied to the shaft 20, thereby causing the table O to be moved back and forth through the arc of a circle past the end of the card A with regular reciprocating movements, and the rolls and cone to be revolved in the direction indidateld diy the arrows. The sliver 12 as it comes from the card is then carried over the cone, and its end passed between the cone and rolls,`j th'e cone continuing to revolve and the bat being produced in a manner which will be readily obvious without a more explicit' description. In forming a bat in this manner it has been found difficult for the workmen tending the machine to so manipulate or guide the sliver onto the foot-pieces e, and also the ankle portions of the cone, as to prevent the bat from being wrinkled and un- To obviate this diffr' even at these points. culty I make use of the compressors b and auxiliary compressors 9 to roll down or even the sliver as it is delivered to the cone, other compressors of a similar character being used when requiredlat other sections of the cone. As the foot-piece stands at an angle, or is inclined to the longitudinal axial line of the cone, the toe of the foot-piece, as it revolves, passes through a larger circle than those portions of the same which are nearer the ankle, and consequently it has to travel at a greater speed. It is therefore necessary, in order to prevent thellc mpressor b from dragging and have it peformI its work in the best manner, to dlividit into sections, which revolve independently and at different rates of speed, according to ltheir locality, that at the outer end of the` arm 32 revolving with greater velocity than the one nearest the shaft w. It is also necessary, in order to keep the coinpressor b in constant contact with the bat on the 1`oot-pieee lu as the cone revolves, that it should be raised or lowered continually, as the case may be, and to accomplish this I attach the arm 32, on which the compressor is journaled, t the r cker-shaft w, and make use of the armi @We unter-balancej, by means of which t 1e 'o |uli-essor is automatically kept in contact with the bat on the foot-piece at all points ol its revolution, the pressure of the compressor on the bat being governed by mov- ICO 1o b are divided.

25 pages ofthe table and its variabile 5o right, as it traverses with greater auxiliary compressors 9 are affect w lenever desired by merely turning the arms S into suchap-osition as to permit their yllintlers to rest 5 npon the bat, and when not required are thrown "ba-.ck or out of contact with the bat, as shown by' the dotted lines 'in Fig. 4. ,lhese compressors are also dividedinto two or more sec- Ationsfor the same reason that the compressors As the table O traverses back and forth through the are of a circle the layers of the sliver Will'be crossed and reerossed, thus greatly strengthening the fabric ot'thc bat, and also ofthe boot, shoe, or st cking formed When the table fi rs either end of its course, its speed is grad ially retarded until it comes to a full stop, and its movement is reversed by the crank l passing the center, after which it is gradually increased until Ait attains its full speed again, and hence, as the cone 4continues to revolve with uniform speed at all times, it is necessary to provide means for preventing the sliver i'rem being` wound unevenly onto the cone by reasui., ai" the stopnoi ements at the ends of its course, as described. i To obviate this difficulty thesuperpospdearriage T is employed, which, While traversing back and forth through the arc of a circle with the table,

3o also hasindependent or differenti al movements imparted to it by the eccentricvli? :ind pitman 3, the eccentric being so constructed and arranged on the shaft N, in connection with the other operative mechanism described, as to 5 cause the carriage to continue to move for a short distance longitudinally al'xtcr the table has stopped and its movement, has been reversed. For instance, if the table is moving from right to left, carrying the carriage with 4Q it, the carriage will also be moved indepeudently in the same direction bntlat a greater speed than the table; and when thetable stops at this end of its course, and is turned back from left to right, the carriage will keep on in 5 its course and override or pass beyond the table a short distance toward the lel't, before its movement is changed; and i'he'r'the, movement o1" the carriage is reversed lby the revolving eccentric I), or changeliltfrom lcftto t Speed than the table, it will overtake it, so to speak, and when the table stops at the right-hand end of its course and is turned baek ,the carriage will keep on in its course and ,averi-idc" or pass beyond the table a short distance toward the rightvbefore its movement is changed, the movements of the carriage in respect to the table being the same at both ends of its course. By varying the size of the eccentric P and 6a its position on the shaft N, the `movements of the carriage may be correspondingly varied. In some machines of this character heretofore constructed the gears for turning` the rolls U have been placed atthe ends of said rolls; but

.in that position they were morci liable to iutcrfere with the bat than when located at the centers, as shown at 6 in Fig. 5, and provided with a proper guard. The carriage has also sometimes been provided with a rack and operated by means of two pini ons adapted to en gage the rack at regular intervals; but this form ot' construction is objectionable, as it necessitates the employment of a long train o mechanism, and renders the working of the machine more irregular and uncertain than when the carriage is operated by means of the eccentric I and pitman 3, as described. 4 carriage rolls and cone are all driven through the medium oi' the shafts G Ii N, and hence their speed docs not vary, or is in one sense uniform at all times with that oi' the card; but the speed ol' the table may be varied, as desired, by using a loose intermediate gear on the stub shaft 2l. and other gears to intermcsh therewith in place of the gearsd ll.

I do not confine myself to using the specific train of mechanism described to produce the reciprocating vibratory movements cf the table, as other means may be employed for that purpose, il" desired; nor to the use ot' the ec centric l, as a crank may be substituted therefor, if preferred; nor to the use ot' the counterbalancej, as a spring may be employ-ed to keep the compressor b in contact with the bat; nor to connecting the eccentric to the carriage by the pitman-rod 3; nor to the use ot' two slaekjoints with the rodj; nor to the use of revolving conlpressors, as they may be i'ast onl their supporti11g-arms, if desired, and ot" any other suitable 'form but,
